Can you try 'KRB5_TRACE=/dev/stderr kvno -S cifs dc1.miovision.corp'?
Ideally, I'd like to see your /etc/krb5.conf, it should have mapping
between AD DNS domain and AD realm so that IPA KDC will be able to route
the ticket request properly to the AD DC. Without that it may assume
miovision.corp belongs to the IPA realm.
